Low alloy steel HC700LA

1. The surface of the cold-rolled plate has a certain gloss and feels smooth to the touch, similar to the common steel water cup used for drinking water. .

2. If the hot-rolled plate has not been pickled, its surface is similar to that of many ordinary steel plates on the market. The rusted surface is red, and the non-rusted surface is purple-black (iron oxide scale). ).

The performance advantages of cold-rolled plates and hot-rolled plates are:

1. Higher precision, the thickness difference of cold-rolled strips does not exceed 0.01~0.03mm.

2. The size is thinner. The thinnest cold-rolled steel strip can be 0.001mm; the thinnest hot-rolled strip can now reach 0.78mm.

3. The surface quality is superior. Cold-rolled steel plates can even produce a mirror surface; while the surface of hot-rolled steel plates has defects such as iron oxide scale and pitting.

4. Cold-rolled plates can adjust their performance such as tensile strength and process performance such as stamping performance according to user requirements.

Cold rolling and hot rolling are two different steel rolling technologies. As the name suggests, cold rolling is rolling steel at room temperature. This kind of steel has high hardness. Hot rolling means steel is rolled under high temperature.
